At the recent K 2007 show in Dusseldorf, Linde Gas Div. of Linde AG, Munich-Pallach, Germany (U.S. office in Murray Hill, N.J.) introduced a method of cooling troublesome hot spots in injection molds where water cooling is ineffective because of restricted space for cooling channels. Using a newly developed control unit, Linde distributes liquid CO2 at high pressure (870 psi) through thin, flexible capillary tubes to hot spots in the mold. There, the CO2 is allowed to expand into a "snow/gas mixture" at about -110 F. The CO is then vented from the mold. Tel: (908) 464-8100 . www.us.lindegas.com
